论文摘要
给出了一种方法来计算空间中无质量耦合标量场的应力能量张量，在该时期中，黑洞从四个维度的球形对称无效壳的塌陷中形成黑洞。该方法的一部分涉及将真空状态的模式与Schwarzschild时空中的完整模式匹配。另一部分涉及从磁场处于真空状态时的应力能量张量的单质表达中减去，当磁场处于异位状态时，相应的表达并将其添加到此范围内的重新归一化的应激量张量。该方法显示在已知结果的二维情况下起作用。
A method is given to compute the stress-energy tensor for a massless minimally coupled scalar field in a spacetime where a black hole forms from the collapse of a spherically symmetric null shell in four dimensions. Part of the method involves matching the modes for the in vacuum state to a complete set of modes in Schwarzschild spacetime. The other part involves subtracting from the unrenormalized expression for the stress-energy tensor when the field is in the in vacuum state, the corresponding expression when the field is in the Unruh state and adding to this the renormalized stress-energy tensor for the field in the Unruh state. The method is shown to work in the two-dimensional case where the results are known.
